Generally turbos can make more boost than you really want—at sea level wastegates release enough exhaust gas that the turbo doesn’t overboost. At higher elevations the wastegate will have less to do and plenty of boost will still be available, especially as the thinner air will be easier to compress. The biggest…

Only the support for the body work.

No doubt some idiots are collecting these things, but this is just a weird example of fetishising any uncommon car. The only reason even one of these shitboxes should be preserved is as a terrible warning.

Yeah, me I'm going to hoon my m4a3e2 Sherman one way down the road, them hoon my 911 back the other way. That way roads will be clear for hooning #2.

You can get compostable 💩 bags.

I’m having a hard time imagining how you geta piston engine to really explode. Catch fire, yes. Throw a rod, yes. Break the crankshaft? Sure, especially if you’re a complete dolt and have a prop strike and somehow manage to get the prop repaired/replaced without the mechanic insisting on sending the engine off to be…

All US naval fighters did have multi speed, multi stage mechanical superchargers. But they were radial rather than inline powered.

The surface to volume ratio of an oil sump is pretty poor for dissipating heat, compared to a radiator. Oil cooler are going to have a lot of little tubes running through a copper heat sink in good airflow--a sump is just a shallow pan, and even if you put fins on it the thing is not that great for getting rid of…

“Also as a side note, remember these engineers never had cars in wind tunnels or studied thermodynamics or dynamic flows”.  It's so sad then that internal combustion engineers from the twenties were so far behind external combustion engineers from the 19th century.

Aircraft engines generally have the heads semi permanently screwed on—the heads are heated up (and the cylinder perhaps chilled), then a vastly expensive device screws the head onto the cylinder. Even valve grinding is done with the head attached.

You can get crankcase, oil pan and cylinder head heaters for modern flat engines. Don't know about turbines or radials. Back in the day, some radial engines had the capability to dilute the oil with avgas for an easier start. You'd then run the the oil temps high enough to evaporate the gas. There were other tricks…

Jesus Christ, that thing is to car styling what “The Phantom Menace” is to films.

I think we can all agree that in that situation the simplest thing is to have the engineers and their managers all shot, pour encourage les autres.  You’ll still be stuck with the shitty, nonreplaceable infotainment system, but the car companies will take the hint and stop doing this shit with the next generation of…

All of these people need to be set on fire, but the asshole who did that to a TVR needs to be set MORE on fire, and slower.

It’s worth noting that Liberty ships had reciprocating steam engines, one of the least efficient types of motor ever produced. That would be a big disincentive to keep the ships running.

Russia was utterly devastating for the Japanese colony in Manchuria, but they had no capability to actually attack the Japanese home islands. WWII Russia was a land power almost exclusively. Think about the effort and specialized equipment that went into Overlord, or the Pacific Marine landings, which the Soviets…

When you’ve got that much horsepower, you’ll do anything you can to give it traction in the air.  Counterrotating props give you twice the traction, plus (as bubbajoe says) efficiency goes up, despite all the energy that goes into wailing.

I wish that District Attorneys in Portland had had the same idea in the early 2000s. Taking an exit by putting your wheel hard over from the left lane should get you jail time, and stopping to let someone make a left from the opposite lane and them accelerating right at them if the person turning moves too fast ought…

Portland here.  I used to see them ALL the time, but new it’s, ‘Look, a Fiat 500!'

First, this car was from the ‘80s, not the ‘60s, so the front brakes are disks not drums (the rear does have toy-sized drums). Not being from the ‘60s, a weber carb was not remotely standard and would never pass smog (the original carb was covered with diaphragms and vacuum hoses and looks quite different). And…
